大家好，我已经集成了 SDWebImage 用于从 Facebook 加载图像。在模拟器上一切正常，但是当我尝试在设备上运行时出现错误：

这次崩溃即将发生：[cell.contactImageView setImageWithURL:[NSURL URLWithString:[[contactList objectAtIndex:indexPath.row] objectForKey:PICTURE_KEY]]placeholderImage:[UIImage imageNamed:@"placeholder.png"]];
我不清楚为什么在模拟器上运行 APP 时会发生这种崩溃。任何帮助，将不胜感激。提前谢谢。
